Display device

Abstract

A display device including a first substrate, a second substrate, and a liquid crystal layer is provided. The liquid crystal layer is disposed between the first substrate and the second substrate. The liquid crystal layer includes a liquid crystal mixture and a nano carbon material. The nano carbon material is distributed in the liquid crystal mixture.

What is claimed is: 
     
         1 . A display device, comprising:
 a first substrate;   a second substrate; and   a liquid crystal layer disposed between the first substrate and the second substrate, wherein the liquid crystal layer comprises:
 a liquid crystal mixture; and 
 a nano carbon material distributed in the liquid crystal mixture. 
   
     
     
         2 . The display device according to  claim 1 , wherein the nano carbon material comprises a plurality of carbon-based nano materials distributed in the liquid crystal mixture. 
     
     
         3 . The display device according to  claim 1 , wherein the nano carbon material comprises a plurality of carbon fibers distributed in the liquid crystal mixture. 
     
     
         4 . The display device according to  claim 1 , wherein the nano carbon material comprises a plurality of carbon graphite materials distributed in the liquid crystal mixture. 
     
     
         5 . The display device according to  claim 1 , wherein the nano carbon material comprises a surface-modified nano carbon material. 
     
     
         6 . The display device according to  claim 5 , wherein a surface of the surface-modified nano carbon material comprises at least one functional group comprising a maleic anhydride group. 
     
     
         7 . The display device according to  claim 1 , wherein the nano carbon material comprises a non-surface-modified nano carbon material. 
     
     
         8 . The display device according to  claim 1 , wherein the weight percentage of the nano carbon material in the liquid crystal mixture is between 0.001˜1%. 
     
     
         9 . The display device according to  claim 1 , wherein the liquid crystal mixture comprises a blue phase liquid crystal mixture. 
     
     
         10 . The display device according to  claim 1 , wherein the liquid crystal layer further comprises a polymer network mixed with the liquid crystal mixture, and the nano carbon material is distributed in the polymer network. 
     
     
         11 . The display device according to  claim 1 , wherein the liquid crystal mixture is optically isotropic when no voltage is applied to the display device.
